I have owned these phones for a number of years now, and have had absolutely no problems with them at all. I have one in the lounge which I use all the time, and the other one in the bedroom for occassional use.
The buttons have a slightly rubbersied feel, but they are quite positive to push, and there is no wearing to the paintwork of the lettering so far. Some of the silver paintwork on the edges of the phone is beginning to look a bit tired but that is from 4 or 5 years constant use (I can often be on the phone for an hour at a time.
There is a button to see who is the last person to call you and if you keep pressing it will show you the last 10 different numbers. You can then just press the call button to return the call to thhe number you have chosen. There is a lso a last number dialed button, if you need to repaeat a recent call. I believe the phone will also hold about 20 numbers in the memory, but I have never bothered to do this because I know all my regular numbers by heart.
There is also a handy button on the charger, which you can press if you dont know where you have left the hand set. It makes the hand set chime regularly until you have found it and cancelled the noise. Perfect for a forgetful person like me.
The other tip I wanted to mention is that about a year ago I started getting problems with the battery life, but this isnt a fault with the phone, merely from excessive use. I thought I'd have to buy a new phone which I was annoyed about, not merel because of the expense, but also because I like my phone, but instead, I ordered some good quality rechargeable aaa batteries from Amazon, the same lithium type that were already in the phone, and hey presto!! the phone is like new again. Really chuffed!!
I signed up for BT's Total Broadband Option 3, and due to the Hub Phone being on backorder, I recieved a pair of BT Calypso 120 cordless telephones. I've never owned cordless phones before, so obviously I was amazed when I could finally walk downstairs with a small device in my hand or on loudspeaker.
Line quality is brilliant, although ringtones aren't excellent. When the line is called, the master base will sound a loud ringtone (which is perfectly audible from downstairs!), along with each handset playing a chosen ringtone. If you loose your handset(s), just hit the "page" button on the master, and the number you have connected to that base will sound.
My only real problem is when the handset is charging, and power is cut to the base. This can sometimes reset the clock, which isn't much of a problme, but it means going out fo your way.
